I got some tubefex worms from a used tank I bought...I never really fed with it before so I thought I would see if my ornate bicher would eat it off my tongs. I tore one cube into 3 pieces and fed it to him...like 2 days in a row...this was this past weekend. Well he stopped eating it after the second day so I thought he didn't like it. He has still been eating but now it seems like his back end wants to float. Those freeze dried worms probably had a lot of air in them....does he now have air traped in him...will it get better if so??? He can still swim to the bottom and sit on the bottom but his back end looks like its hovering off the ground and when it swims some and floats in the current it seems the back is wanting to float higher than the head. Am I paranoid...or did I just mess the little guy up
